TO. ALL WHOM IT MAY CONCERN:

Be it known that I, Cannes H. ALsor, of Middletown, in the county ofMiddlesex, and State of Connecticut, have invented a new and usefulImprovement in Breech-Loading Fire-Arms; and that the followingdescription, taken in connection with the accompanying drawings,hereinafter referred to, forms a full and exact specification of thesame, wherein I have set forth the nature and principles of my saidimprovement, by which my invention may be distinguished from all othersof a similar class, together with such parts as I claim, and desire tohave secured to me by Letters Patent. p

This invention consists in a novel manner-of constructing the breech,and applying the barrels thereto, and in a peculiar fastening or catchfor the barrels, as hereinafter fully shown and described, whereby thepiece may be loaded or charged with the greatest facility, and the partsrendered very permanent and durable. In the accompanying sheet'ofdrawings Figur e 1 is a longitudinal section of my invention, taken inthe line :a x, fig. 2.

2, a plan or top view of the saine, the barrels of the piece being in aforward position-on the plate or bar of the breech, ready for loading.

Figure 3, a transverse section of the same, taken in the line 3/ y, fig.1.

Similar letters of reference indicate like parts,

AYr-epresents the breech, which is constructed with a plate or bar, B,extending forward, and forming a bed for the rear part of the barrels,C, to rest and slide upon,the plate or bar and the breech being all inone piece. The plate or bar has a groove, a, made longitudinally andcentrally in its.upp'er surface,and of circular form,

as shown in fig. 3, and in this groove audit, 6, at the under side ofthe barrels C, is fitted, and allowed to slide freely, aspiral spring,0, being placed dnthe groove a, between the end of the rib b and therear of the groove a, (see more particularly fig. 1.) F

At the rear ends of the bar-rails it here is a lip, D, which extendsbackward, and is perforated with a hole, d. This lip, when the ends ofthe barrels C are in contact with the breech A, is in an. opening, e, inthe breech, and has the lower end of a pin, E,'flitted in it. This pinis fitted vertically inthe breech, is allowed to slide freely therein,and is connected a pivot, f, to a lever, SE, underneath the tongue orshank g of the breech, It being the fulcrum-pin of the lever. 'Thislever has a spring, z, bearing upon it, whichhas a tendency to keep thepin E in the perforation nf 'the lip D. a

In order to load the piece, the rear end of the lever F is pressed downbyil earing upon a pm, j, which extends up through the tongue or shankg, the lower end of said pin being pivoted to the lover. The pin E isthereby raised out from the perforation in the lip D, and the spring 0throws the ibarrels C vfiw'ward on the-plate or bar 13, so that thechange or cartridges may be readily inserted in the rear ends of thebarrels. The barrels C are then drawn back, and the lip D enters theopening e, shoves up the pin E, which is provided with a bevelled lowerend, the pin, under the influence of the "spring a, dropping intotihzelhole d of the lip, when said hole comes in line with the pin. Thepiece isthen ready for firing.

I claim as new, and desire to secureby Letters Patent- 1. The spiralspring 0, in combination with the groove a in the plate IS, the rib 6,upon the under side of the barrels, the perforated lip Dfand thevertical pin'E, having a bevelled end, all arranged as described,-

whereby, as the pin E israised by the spring-lever F, the spring 1:throws the barrels forward, for the insertion of the cartridge, asherein shown and described. A

2. The catch or fastening, colnposed of the vertical pin or bolt E, iiftted .in the breech, and pivoted to the spring-lever F, in combinationwith the perforated lip D, at the under side of the rear of the barrelor barrels, and the recess e in the breech, to receive the lip, allarranged substantially as and for the purpose specified.
